Before singing 'Supercollider', Yorke told the crowd: "This song is for Jack White.

"We saw him yesterday. A big thank you to him, but we can't tell you why. You'll find out."

White has since told BBC Radio 6 Music: "I don't know how much to tell about it. I didn't play with him or produce but they came and recorded at Third Man but I don't know how much more they want to be said about that. That's probably all I can say."
